A novel adaptive unscented Kalman filter (AUKF) based estimation algorithm is proposed for a 3U Cubsat. This small satellite employs a three axis magnetometer and three MEMS gyroscopes as well as three magnetic torque rods and one reaction wheel on the pitch axis. Unlike the existing UKF, in this paper, an n+1 sigma set is used to estimate the nanosatellite attitude instead of 2n + 1 sigma poin...
The HAUSAT-2 is a 30kg class nanosatellite which is stabilized by 3-axis active control method. Its main mission objectives are to provide studying the scope of activity and ecology of animals using Animal Tracking System (ATS) and collecting the space information data of mission orbit from Electric Plasma Probe (EPP) as a space science payload. 2-axes sun sensors, 3-axes magnetometer, and star...
There is now a body of evidence to indicate that coupling occurs between the lithosphere–atmosphere–ionosphere prior to earthquake events. Nevertheless the physics of these phenomena and the possibilities of their use as part of an earthquake early warning system remain poorly understood. Proposed here is a programme to create a much greater understanding in this area through the deployment of ...
Current GPS technologies for satellite navigation are relatively costly, heavy, and utilize a high amount of power. This makes such systems difficult for small satellites to support. In this paper, we describe a lowcost, low-weight, low-power GPS navigation system to support smaller satellites. A key component of our solution involves our patented TIDGET-based receiver design, which takes a bri...
